1、Designation: E 2663 08Standard Practice forDigital Imaging and Communication in NondestructiveEvaluation (DICONDE) for Ultrasonic Test Methods1This standard is issued under the fixed designation E 2663; the number immediately following the designation indicates the year oforiginal adoption or, in th
2、e case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice facilitates the interoperability of ultrasonicimaging equipment by speci
3、fying image data transfer andarchival storage methods in commonly accepted terms. Thisdocument is intended to be used in conjunction with PracticeE 2339 on Digital Imaging and Communication in Nondestruc-tive Evaluation (DICONDE). Practice E 2339 defines an in-dustrial adaptation of the NEMA Standar
4、ds Publication titledDigital Imaging and Communications in Medicine (DICOM,see http:/medical.nema.org), an international standard forimage data acquisition, review, transfer and archival storage.The goal of Practice E 2339, commonly referred to as DI-CONDE, is to provide a standard that facilitates
5、the display andanalysis of NDE test results on any system conforming to theDICONDE standard. Toward that end, Practice E 2339 pro-vides a data dictionary and set of information modules that areapplicable to all NDE modalities. This practice supplementsPractice E 2339 by providing information object
6、definitions,information modules and data dictionary that are specific toultrasonic test methods.1.2 This practice has been developed to overcome the issuesthat arise when analyzing or archiving data from ultrasonic testequipment using proprietary data transfer and storage methods.As digital technolo
7、gies evolve, data must remain decipherablethrough the use of open, industry-wide methods for datatransfer and archival storage. This practice defines a methodwhere all the ultrasonic technique parameters and test resultsare communicated and stored in a standard format regardless ofchanges in digital
8、 technology.1.3 This practice does not specify:1.3.1 A testing or validation procedure to assess an imple-mentations conformance to the standard.1.3.2 The implementation details of any features of thestandard on a device claiming conformance.1.3.3 The overall set of features and functions to be ex-p
9、ected from a system implemented by integrating a group ofdevices each claiming DICONDE conformance.1.4 Although this practice contains no values that requireunits, it does describe methods to store and communicate datathat do require units to be properly interpreted. The SI unitsrequired by this pra
10、ctice are to be regarded as standard. Noother units of measurement are included in this standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health
11、practices and determine the applica-bility of regulatory limitations prior to use.2.
